Search Results<span>Let L denote the line of intersection. Then v = a × b = (1 − 1,−(−2 − 1),2 − (−1)) = (0,3,3) is parallel to L. We only need to find a point P on L. To find P, solved the system of equations of the planes: 2x − y + z = 5 and x + y − z = 1. We consider P to be the point of L on the plane z = 0.</span>
Answer:
The test is left - tailed
We cannot reject the organization's claim ( its cheapest screens will truly last less than 2.8 years)
Step-by-step explanation:
Sample size, n = 61
Sample mean,
Standard deviation,
Significance level, α=0.02
Null hypothesis,
Alternative hypothesis,
It is clearly seen from the alternative hypothesis, that it is a left tailed test. It is not tailed towards the two directions.
Calculate the test statistic:
Calculate the P-value:
P(Z < -3.35) = 0.0002
Since (p-value = 0.0002) < (α=0.02), the null hypothesis is rejected.
It can therefore be concluded that the mean of the cheapest screen is less than 2.8 years. i.e. the cheapest screen will last less than 2.8 years
Bisected means half, so just divide by 2:
15 degrees
Answer:
Inherently asymmetrical casual relationship.
Step-by-step explanation:
The dog owners are given free dog food samples which contain new vegetables. These samples are given to them by organizing booths at the dog events. The reaction of the dog owners is observed towards this new dog food. This an example of inherently asymmetrical relationship.
Do you Mean
(6²)x = 1
if yes then x =1/(6²) = 6-² or 1/36
also (6^0)x= 1
recall 6^0 = 1
so you have 1x=1
x=1
